Issue with wireless networking

I have been having trouble with my laptop connecting to the internet. I have no Ethernet card, so Wireless is the only internet source for this computer. The wireless card is a BCM4306 Wireless LAN Controller from Broadcom Corp. I have been unable to get the wireless to work.

I have tried the Troubleshooting Page and done everything it says to do. I get caught up at "Check for a connection to the router."

I have tried looking at the WPA Page as well. I don't know if there is something wrong with my driver, or if I need to install ndiswrapper, or if it's some incompatability with the network I'm trying to connect to (I'm in a Library so I can't access or edit the network).

I like Linux, but if I can't get this fixed before school starts in August, I'm going to have to go back to Windows XP.
